TGC1439A Typical RF Performance (Fixtured)
The TriQuint TGC1439A-EPU is a 5-Bit Digital Phase
Shifter MMIC design using TriQuint鈥檚 proven 0.5
碌m
Power pHEMT process to support a variety of K-Band
phased array applications including satellite
communication systems.
The 5-bit design utilizes a compact topology that
achieves a 1.27 mm
2
die area, high performance and
good tolerance to control voltage variation
The TGC1439A provides a 5-Bit digital phase shift
function with a nominal -5 dB insertion loss and 3潞
RMS phase shift error over a bandwidth of 18-20 GHz.
The TGC1439A requires a minimum of off-chip
components and operates with a -5.0 V to -2.5 V
control voltage range. Each device is RF tested on-
wafer to ensure performance compliance. The device
is available in chip form.
